Jimmy Piersall (born November 14, 1929 in Waterbury, Connecticut) is a former center fielder in Major League Baseball. Between 1950 and 1967, he played for the Boston Red Sox (1950, 1952-58), Cleveland Indians (1959-61), Washington Senators (1962-63), New York Mets (1963) and Los Angeles & California Angels (1963-67).

While he had a fairly good professional career as a center fielder, Piersall is better known for his well-publicized battle with bipolar disorder which became the subject of the movie Fear Strikes Out.
